Yes Vertigo does get worse with movment. Have you ever had an MRI done on your brain? I know a small number of people do get vertigo simply by having Lupus. Because Lupus can attack your brain anywhere it wants to.
As far as the plane goes of course every one is different but I have flown with ear infections and had no problem. You might try taking a decongestant and bring some cotton ball with you just in case. You have been mentioning this problem with vertigo for a while now. I would almost bet the farm it's not an inner ear problem and more a lupus brain/vertigo problem. Have you checked you meds to see if vertigo is a side effect of any of them? I don't know how you are fixed with insurance but if all possible you really need a brain scan especially if it's starting to effect your ability to drive.
